L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant au dessin an nexé qui représente un schéma synoptique illustrant un moteur Diesel de véhi cule automobile, et les différents organes associés à celui-ci. The invention will be better understood on reading the description which will follow, given solely by way of example and with reference to the appended drawing which represents a block diagram illustrating a diesel engine of a motor vehicle, and the various organs associated with it.

On a en effet représenté sur cette figure, un moteur Diesel de véhicule automobile qui est désigné par la référence générale 1. It has in fact shown in this figure, a motor vehicle diesel engine which is designated by the general reference 1.

Ce moteur Diesel est associé à des moyens d'admission d'air en en trée de celui-ci, qui sont désignés par la référence générale 2. This diesel engine is associated with air intake means in trea thereof, which are designated by the general reference 2.

En sortie, ce moteur est associé à une ligne d'échappement qui est désignée par la référence générale 3. At the output, this engine is associated with an exhaust line which is designated by the general reference 3.

Des moyens de recyclage de gaz d'échappement du moteur en entrée de celui-ci sont également prévus et sont désignés par la référence générale 4. Ces moyens sont alors interposés par exemple entre la sortie du mo teur et les moyens 2 d'admission d'air dans celui-ci. Means for recycling the engine exhaust gas at the inlet thereof are also provided and are designated by the general reference 4. These means are then interposed for example between the output of the motor and the means 2 of admission d in this one.

La ligne d'échappement peut également être associée à un turbocom presseur désigné par la référence générale 5 et plus particulièrement à la portion de turbine de celui-ci, de façon classique. The exhaust line may also be associated with a turbocompressor designated by the general reference 5 and more particularly to the turbine portion thereof, in a conventional manner.

Enfin, la ligne d'échappement comporte un catalyseur d'oxydation dé signé par la référence générale 6, disposé en amont d'un filtre à particules dési gné par la référence générale 7, dans la ligne d `échappement. Finally, the exhaust line comprises an oxidation catalyst dsigned by the general reference 6, disposed upstream of a particulate filter designated by the general reference 7, in the exhaust line.

Le moteur est également associé à un système d'alimentation com mune en carburant des cylindres de celui-ci. Ce système est désigné par la réfé rence générale 8 sur cette figure et comporte par exemple des injecteurs à com mande électrique associés à ces cylindres. Dans l'exemple de réalisation représenté, le moteur est un moteur à quatre cylindres et comporte donc quatre injecteurs à commande électrique, res pectivement 9,10,11 et 12. The engine is also associated with a common fuel supply system for the cylinders thereof. This system is designated by the general reference 8 in this figure and comprises for example electric control injectors associated with these cylinders. In the exemplary embodiment shown, the engine is a four-cylinder engine and therefore comprises four electrically operated injectors, respectively 9,10,11 and 12.

Ces différents injecteurs sont associés à une rampe d'alimentation commune en carburant désignée par la référence générale 13 et reliée à des moyens d'alimentation en carburant désignés par la référence générale 14, com prenant par exemple une pompe à haute pression. These different injectors are associated with a common fuel supply ramp designated by the general reference 13 and connected to fuel supply means designated by the general reference 14, including for example a high pressure pump.

Ces moyens d'alimentation sont reliés à un réservoir de carburant dé signé par la référence générale 15 et à des moyens d'ajout à ce carburant d'un additif destiné à se déposer sur le filtre à particules pour abaisser la température de combustion des particules piégées dans celui-ci. These supply means are connected to a fuel tank ds signed by the general reference 15 and means for adding to this fuel an additive intended to be deposited on the particle filter to lower the combustion temperature of the particles trapped in this one.

En fait, cet additif peut par exemple être contenu dans un réservoir auxiliaire désigné par la référence générale 16 associé au réservoir de carburant 15, pour permettre l'injection d'une certaine quantité de cet additif dans le carbu rant. In fact, this additive may for example be contained in an auxiliary tank designated by the general reference 16 associated with the fuel tank 15, to allow the injection of a certain amount of this additive into the fuel.

Enfin, ce moteur et les différents organes qui viennent d'être décrits sont également associés à de moyens de contrôle de leur fonctionnement dési gnés par la référence générale 17 sur cette figure, comprenant par exemple tout calculateur approprié 18 associé à des moyens de stockage d'informations 19, et raccordé en entrée à différents moyens d'acquisition d'informations relatives à différents paramètres de fonctionnement de ce moteur et de ces organes, ce cal culateur étant alors adapté pour contrôler le fonctionnement des moyens d'admission, des moyens de recyclage, du turbocompresseur et/ou du système d'alimentation pour piloter le fonctionnement du moteur et notamment le couple engendré par celui-ci en fonction des conditions de roulage du véhicule, de façon classique. Finally, this motor and the various components that have just been described are also associated with means for controlling their operation designated by the general reference 17 in this figure, comprising, for example, any appropriate computer 18 associated with storage means. information 19, and input connected to different means of acquisition of information relating to different operating parameters of the engine and these bodies, this calculator being then adapted to control the operation of the admission means, means of recycling, the turbocharger and / or the power system to control the operation of the engine and in particular the torque generated by it according to the driving conditions of the vehicle, in conventional manner.

C'est ainsi par exemple que ce calculateur est relié à un capteur de pression différentielle 20 aux bornes du catalyseur et du filtre à particules, res pectivement 6 et 7, à des capteurs de température 21,22 et 23, respectivement en amont du catalyseur, entre ce catalyseur et le filtre à particules et en aval de ce filtre à particules dans la ligne d'échappement. For example, this calculator is connected to a differential pressure sensor 20 at the terminals of the catalyst and of the particulate filter, respectively 6 and 7, at temperature sensors 21, 22 and 23 respectively upstream of the catalyst. between this catalyst and the particulate filter and downstream of this particulate filter in the exhaust line.

Le calculateur peut également recevoir une information de teneur en oxygène des gaz d'échappement à partir d'une sonde Lambda #. proportionnelle désignée par la référence générale 24 sur cette figure, intégrée dans la ligne d'échappement. The calculator can also receive oxygen content information of the exhaust gas from a Lambda # probe. proportional indicated by the general reference 24 in this figure, integrated into the exhaust line.

En sortie, ce calculateur est adapté pour piloter les moyens d'admission d'air, les moyens de recyclage de gaz d'échappement, le turbocom presseur, les moyens d'ajout au carburant de l'additif, les moyens d'alimentation en carburant de la rampe commune et les différents injecteurs associés aux cy lindres du moteur. At the output, this computer is adapted to control the air intake means, the exhaust gas recycling means, the turbocompressor, the means for adding fuel to the additive, the feed means for fuel of the common rail and the various injectors associated with the engine cylinders.

En particulier, ce calculateur est adapté pour déclencher une phase de régénération du filtre à particules par combustion des particules piégées dans celui-ci en enclenchant une phase d'injections multiples de carburant dans les cylindres du moteur pendant leur phase de détente. In particular, this computer is adapted to trigger a regeneration phase of the particulate filter by combustion of the particles trapped therein by engaging a phase of multiple injections of fuel in the cylinders of the engine during their expansion phase.

Les particules émises par le moteur au cours de son fonctionnement sont en effet piégées dans le filtre à particules. II convient alors de régénérer ce lui-ci régulièrement par combustion de ces particules. The particles emitted by the engine during its operation are indeed trapped in the particulate filter. It is then necessary to regenerate it regularly by combustion of these particles.

Avantageusement, les moyens 4 de recyclage des gaz d'échappement du moteur en entrée de celui-ci comprennent une électrovanne proportionnelle qui est pilotée par les moyens de contrôle 17 en fonction des in formations délivrées par la sonde Lambda a, 24, pour réguler le recyclage des gaz en fonction de la teneur en oxygène des gaz d'échappement, lors de la phase de régénération du filtre à particules. Advantageously, the means 4 for recycling the engine exhaust gas at its inlet comprise a proportional solenoid valve which is controlled by the control means 17 as a function of the information supplied by the Lambda probe a, 24, to regulate the recycling of gases according to the oxygen content of the exhaust gas during the regeneration phase of the particulate filter.

Ceci permet alors notamment de mieux contrôler le déroulement de la régénération du filtre par combustion des particules.This then allows in particular to better control the progress of the regeneration of the filter by combustion of the particles.
